Laboratory/Project/Term Paper:

Students work individually or in small groups on a course project. The projects will complement and extend the lecture material. The project may include: (1) implementation of a network protocol, or (2) proposal/design of a new protocol or extension of an existing one followed by its evaluation via computer simulation (and mathematical analysis, whenever possible). Students therefore gain hands-on experience in network protocol design, development, and analysis.

Engineering Design Statement:

The course project includes design, development, and implementation issues in computer network protocols and architectures. Lectures discuss various design issues in computer networks, implementation of the protocols, and tradeoffs between various performance measures such as delay and thruput. The homework and exam problems are based on design issues discussed in lecture.
